Give examples of linear equations in one variable with one solution (π₯ = π), infinitely many solutions (π = π), or no solutions (π = π). Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form π₯ = π, π = π,ππ π = π results (where π and π are different numbers).

Expressions and Equations

- Analyze and solve linear equations and inequalities.
Fluently (efficiently, accurately, and flexibly) solve one-step, two-step, and multi-step linear equations and inequalities in one variable, including situations with the same variable appearing on both sides of the equal sign.
